Lac Fourchu Airfield

Not applicable. As the airfield most likely never existed, it was not closed for any specific reason. The listing in some non-official databases is considered to be an error, a data artifact, or a fictional creation, possibly for flight simulation purposes.

The site at the specified coordinates (45.058056, 5.933056) is a natural, high-altitude alpine environment surrounding the lake Lac Fourchu. It is located within the Belledonne mountain range at an elevation of approximately 2,060 meters (6,760 feet). The area is a protected Natura 2000 site, recognized for its ecological value, and is a popular destination for hiking and nature tourism. There is no infrastructure present other than hiking trails.

The site has no known historical significance as an airfield. A thorough review of historical and current aerial photography (including from France's IGN) and official aviation records shows no trace of a runway, taxiway, or any aviation-related infrastructure. The designation 'FR-0486' is not an official ICAO code and appears only in user-generated, non-official databases. The location itself is a high-altitude, rugged mountain area entirely unsuitable for aviation operations.

There are zero plans or prospects for 'reopening' this airfield, as it is not a recognized or historical aviation site. The construction of an airfield at this location would be technically infeasible and legally impossible due to the extremely challenging mountainous terrain, high altitude, and its status as a protected natural environment.
